    • All solid-state spectral broadening: An average and peak power scalable method for compression of ultrashort pulses 

      Seidel, Marcus; Arisholm, Gunnar; Brons, Jonathan; Pervak, Vladimir; Pronin, Oleg (2016)
      Spectral broadening in bulk material is a simple, robust and low-cost method to extend the bandwidth of a laser source. Consequently, it enables ultrashort pulse compression. Experiments with a 38 MHz repetition rate, 50 ...

    • Efficient High-Power Ultrashort Pulse Compression in Self-Defocusing Bulk Media 

      Seidel, Marcus; Brons, Jonathan; Arisholm, Gunnar; Fritsch, Kilian; Pervak, Vladimir; Pronin, Oleg (2017)
      Peak and average power scalability is the key feature of advancing femtosecond laser technology. Today, near-infrared light sources are capable of providing hundreds of Watts of average power. These sources, however, ...

    • Few-cycle pulse generation by double-stage hybrid multi-pass multi-plate nonlinear pulse compression 

      Viotti, Anne-Lise; Li, Chen; Arisholm, Gunnar; Winkelmann, Lutz; Hartl, Ingmar; Heyl, Christoph M.; Seidel, Marcus (2023-02-10)
      Few-cycle pulses present an essential tool to track ultrafast dynamics in matter and drive strong field effects. To address photon-hungry applications, high average power lasers are used which, however, cannot directly ...

    • High-energy bow tie multi-pass cells for nonlinear spectralbroadening applications 

      Heyl, Christoph M.; Seidel, Marcus; Escoto, Esmerando; Schönberg, Arthur; Carlström, Stefanos; Arisholm, Gunnar; Lang, Tino; Hartl, Ingmar (2022-01-24)
      Multi-pass cells (MPCs) have emerged as very attractive tools for spectral broadening and post-compression applications. We discuss pulse energy limitations of standard MPCs considering basic geometrical scaling principles ...

    • Multi-gigawatt peak power post-compression in a bulk multi-pass cell at a high repetition rate 

      Raab, Ann-Kathrin; Seidel, Marcus; Guo, Chen; Sytcevich, Ivan; Arisholm, Gunnar; L’Huillier, Anne; Arnold, Cord L.; Viotti, Anne-Lise (2022-09-27)
      The output of a 200 kHz, 34 W, 300 fs ytterbium amplifier is compressed to 31 fs with >88% efficiency to reach a peak power of 2.5 GW, which to date is a record for a singlestage bulk multi-pass cell. Despite operation ...

    • Multi-watt, multi-octave, mid-infrared femtosecond source 

      Seidel, Marcus; Xiao, Xiao; Hussain, Syed A.; Arisholm, Gunnar; Hartung, Alexander; Zawilski, Kevin T.; Schunemann, Peter; Habel, Florian; Trubetskov, Michael; Pervak, Vladimir; Pronin, Oleg; Krausz, Ferenc (2018)
      Spectroscopy in the wavelength range from 2 to 11 μm (900 to 5000 cm−1) implies a multitude of applications in fundamental physics, chemistry, as well as environmental and life sciences. The related vibrational transitions, ...

    • Ultrafast Pulse Compression in Bulk with > 20 Times Spectral Broadening Factor from a Single Stage 

      Seidel, Marcus; Balla, Prannay; Arisholm, Gunnar; Winkelmann, Lutz; Hartl, Ingmar; Heyl, Christoph M. (2021-11-01)
      We introduce the combination of multi-pass cell and multi-plate spectral broadening. We demonstrate the compression of 110-μJ pulses from 900-fs to 60-fs in a single stage and report broadening to 38-fs transform-limit by ...
